ANTISKID-CHAIN TIGHTENER.

.pplicaton filed March 6, 1928. Serial No. 623,224.

To all 107mm t may concern.'

Be it known that l, Grenen B. HnAfH-rnamoron, a citizen ot the UnitedStates, residing` at Oakland, in the county of Pottawattamie and Stateof iowa, have invented certain new and usetul Improvements inAntiskid-Chain Tighteners; and l do hereby declare the following to be afull, clear,l

and exact description ot the invention, such as will enable othersskilled .in the art to which it appertains to make and use the same.

The invention has `tor its object the provision of means wherebyanti-skid chains, when applied to the wheel of a motor vehicle, may betightened to facilitate the adjustment both when applying and removingthe chains, thereby preventing the loosening of the chains when inservice and obviating the annoyance incident to a loose chain strik.-ing the fender or other' part of the vehicle.

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

lWhile the drawings illustrate an embodiment of the invention, it is tobe understood that .in adapting the same to meet different conditionsand requirements, various changes in the form` proportion and minordetails oi construction may be resorted to'without departing trom thenature of the invention.

Referring to the accompanying drawings 'forming part of the application,

Figure 1 is side view of an antiskid chaintightener embodying theinvention,

Figure 2 is a longitudinal section thereof, and

Figure S a cross section on the line 3-3 of 'Figure 1.

Corresponding and like parts are referred to in the followingdescription and desig nated in the several views of the drawings by likereference characters.

The device comprises a` tubular member l having a spur 2 at one end anda longitudi nal enlargement at one side in which is formed a groove 4which opens into the space of the member. The opposite end of the memberl is reduced. as indicated at 5. The member 1 may be cast or `formed inany preferred way. l

A companion member 6 of flattened form is slidable longitudinally withinthe member Il the groove 4c of the lateral extension 2. A spur 7 isprovided at one end of the member 6 and is adapted to cooperate with thespur 2 to engage opposite end portions oit the chains to be tightened,which are drawn together by advancement of the member 6 within themember 1. A threaded stem 8 projects longitudinally from the oppositeend ot the member and is adapted to pass loosely through the reduced end5 of the member l. A hand nut 9 threaded upon the stem 8 engages thereduce-d end 5 of the member 1 and serves to dra-w the member 6 withinthe member 1 when the tool is in operation to tighten an anti-skid chainabout a wheel ot a motor vehicle. The member 6 may be cast or formed inany preferred way.

The tool is adapted as an adjunct to the kit ot tools usually providedfor a` motor vehicle and when it is required to tighten an anti-skidchain about the wheel, the spurs 2 and 7 engage links at opposite endsoi the chain in the rear of the terminal links or fastening elements,and when the member 6 is drawn within the member l, the spurs 2 and 7are drawn together and correspondingly draw opposite end positions ofthe chain and tighten the same about the wheel, thereby facilitatingboth the application and the removal ot the antiskid chains as required.

That is claimed is:

A. device of the class described consisting of a tube-like member madein a single piece.y a bar-like member made in a single piece. eachmember having a spur, the second member having a 'dat portion for partof its length and a reduced screw threaded shank extending 'from thevflat portion, the first member having a longitudinally oltset enlargement providing a groove receiving the flat portion beyond theshank. the first member having a tubular reduced portion disaligned withand beyond the enlargement snugly fit by said shank, the end of the en-llargement adjacent said reduced portion be .ing closed, and ay nutoperable on said shank and against said reduced portion.
